To run the service in console mode, you need to use the //TS// parameter. The service shutdown can be initiated by pressing CTRL+C or CTRL+BREAK. If you rename the tomcat8.exe to testservice.exe then you can just execute the testservice.exe and this command mode will be executed by default.
Run the service named ‘Tomcat8’ in console mode
C:\> tomcat8 //TS//Tomcat8 [additional arguments]
